Well, this is one of those rare cases where I don't agree with Wolf. I would not assign human meaning to tones of parrot's vocalizations because an ascending tone at the end does not necessarily mean a question as it does in human language. I'll be honest with you, I don't know what these vocalizations mean. I don't know if they are asking you for food or simply calling or maybe just talking to themselves but I doubt it's the name they assigned to you because, for one thing, parrots don't really assign names to other animals or birds, the only time they do it is when they name their babies. They use the name the other parrot uses for itself (which is either identical to the one the parents gave it or very similar -sometimes they tweak it a bit, just like a human would say his name is Mike when his parents named him Michael). So a parrot that encounters a second parrot he doesn't know will say his own name to him as a way of introducing himself and the second parrot will then use this name to refer to him. But the second parrot would not make up a name for the first one. Parrots do learn their human name and would call themselves this name but, sometimes, they get confused -like when a parrot says "Hello" first thing and people think the parrot is greeting them but, in reality, the parrot thinks that Hello is his name and he is very politely introducing himself (I have an amazon that says "Hello" when I start feeding and have not gotten to him yet because he thinks that's his human name so he is telling me "Hey, Hello is here, don't forget me" - and I have one that thinks his name is "Hi, Zachary" instead of just Zachary).
If the parrot stops making the second noise when you approach it or makes it when you are feeding a treat to the hen, then I would say that there is a possibility that this is his own name so why don't you try saying his human name to him? By the way, does he know his human name?
